(Cl. 33-50) This invention relates to mounts for gun sights and more particularly to a mount for telescopic sights which permits pivoting the sight out of position for an open sight, replacement or removal of the telescopic sight without effecting adjustments thereto.

Although there are many sights mounted in a manner that permits relatively quick removal from the line of sight, and also some mounts which permit relatively ready removal of the sight from the gun, none of such gun sight mounts embody both such feautres and permit adjustment of the sight which remains unaffected when the sight is swung out of the line of sight, or replaced or removed from the gun.

In addition, the subject mount while permitting normal removal without requiring removal of pins or the like, can be removed in an emergency against a spring bias.

It is an object of this invention provide a mount for telescopic gun sights which permits removal or replacement of the sight with no disturbance of linear adjustments normally required.

Another object of this invention Mis vt provide-the above type gun`sight-mountwhichiscapaple of being swung Another object of this invention is to provide a gun sight mount which has separable parts, one connected to the gun and the other supporting the sight.

Another object of this invention is to provide a gun sight mount of the type described wherein the two portions are hinged to one another and the hinge forms the separable connection.

'Ihe foregoing and other objects and advantages of the invention will appear more fully hereinafter from a consideration of the detailed description which follows, taken together with the accompanying drawings several embodiments of the invention are illustrated by way of example. It is to be expressly understood, however, that the drawings are for illustration purposes only and are not to be construed as defining the limits of the invention.

FIGURE 1 is a plan view of the novel gun sight mount with the sight pivoted 90 degrees out of the line of sight.

FIGURE 2 is a side elevation of the gun sight mount of FIGURE l with the sight positioned for use.

FIGURE 3 is an exploded view of the pivot and release parts of the novel gun sight mount.

FIGURE 4 is an exploded View of a modification of the novel gun sight mount of FIGURES 1 and 2.

FIGURES 5 and 6 are endviews of the novel gun sight mount as shown in FIGURES 1 and 2, respectively.

Now referring to the drawings, the novel sight mount has a plate to be connected to a gun (not shown) by a plurality of screws 11. Plate 10 has a forward lug 12 which mounts a ball member 13 that engages a screw 14 which when rotated linearly adjusts the ball member 13 for elevation adjustments of a sight 21. Plate 10 also has a rear lug 15, similar to lug 12, which mounts a ball member 16 that engages a screw 17 which when rotated linearly adjusts the ball member 16 for azimuth adjustments.

The novel mount has a second major portion of the form of a clamp plate 20 to receive the sight 21 which is held therein by clamp members 22 fixed in position by screws 23. Plate 20 has a pair of lugs 24 and 25 that are spaced from each other and mount ball seats 26 and 27, respectively, which receive the respective ball members 13 and 16. Seat 27 has a threaded shank 28 on which a screw wheel 29 is threaded and held against axial 'ice movement by spring 31 that seats against lug 24. When screw Wheel 29 is rotated, seat 27 moves axially and is itself kept from rotating by a keeper pin 30.

It should be readily seen that when plate 20 is moved backwardly or to the right on the drawing, seat 26 moves away from ball member 13 and the plates 10 and 20 may then be separated. The ball members 13 and 16 in seats 26 and 27, respectively, also provide a hinge for pivoting plate 20 to move sight 21 out of the line of sight. By rotating the wheel 29, seat 27 can be moved out of contact with ball member 16 to also separate the mount. It should be understood that seat 26 and seat 27 with spring 31 and wheel 29 may be reversed. Further, by reversing the relative positions of spring 31 and wheel 29, separation by overcoming spring bias can be locked out.

On plate 10 may be mounted an adjustable open sight plate 18 by a pair of screws 19. The open sight 18 is uncovered for use when sight 21 is pivoted out of the line of sight or when removed.

To prevent free pivoting of plate 20, a spring 32 is connected thereto with a free end that engages a groove 33 in the plate 10, as may be clearly seen in FIGURES 5 and 6. To insure correct positioning of the sight 21, a screw 34 is disposed in each end of plate 10 which forms an adjustable seat contacted by plate 20 when sight 21 is in position for use.

A moditied form of the novel mount is illustrated in FIGURE 4 wherein the plate 10 of FIGURES 1 and 2 is now a two plate arrangement 35 and 36.

While this invention has been described with particular reference to the construction shown in the drawing, it is to be understood that such is not to be construed as imparting limitations upon the invention, which is best deiined by the claims appended hereto.

Hav-ing thus described my invention, I claim as new and desire to secure by Letters Patent:

1. A gun sight mount comprising a plate to be connected to a gun and`laving a pair of spaced ball members, a clamp plate to receive and` support aigunpsight and having a pair of ball seats to rec'ivethe ball mi bers to permit pivoting of the plates relative to one another, one of said seats having a threaded shank, a screw wheel threadedly engaging said shank for axially adjusting the seat with such shank relative to the other seat when rotated, spring means encircling said ,shank and disposed under compression between said plate to be connected to the gun and said wheel for biasing the seat with said shank such that axial movement of the plates relative to one another moves the other seat away from its ball member to separate the plates, and an open sig-ht adjustably supported on the plate connected to the gun that is uncovered for use when the clamp plate is moved to move the sight out of position for use.

2. A gun sight mount according to claim l in which one of the ball members is slidable relative to the plate to be connected to the gun, and a rotatable member fixed against axial movement in the plate to be connected to the gun and threadedly engaging the slidable ball member for linearly adjusting such ball member in azimuth when rotated to adjust the azimuth setting of the sight that is unaffected by relative movement between the plates.

3. A gun sight mount according to claim 1 in which one of the ball members is slidable relative to the plate to be connected to the gun, and a rotatable member xed against axial movement in the plate to be connected to the gun and threadedly engaging the slidable ball member for linearly adjusting such ball member in elevation when rotated to adjust the elevation setting of the sight that is unaffected by relative movement between the plates.

4. A gun sight mount according to claim 1 in which both ball members are slidablerelative to the plate to be vonnected to the gun, a pair of rotatable members xed against axial movement in the plate to be connected to the gun, one of the rotatable members threadedly engaging one of the ball members for linearly adjusting such ball member in azimuth when rotated to adjust the azimuth setting of the sight, and the other of said rotatable members threadedly engaging the other of said ball members for linearly adjusting such other ball member in elevation when rotated to adjust the elevation setting of the sight, said settings being unaffected by relative movement between said plates.
